Some users of Nvidia's GeForce graphics cards are noticing severe performance issues after installing the Windows 11 2022 Update (aka Windows 11 22H2) that Microsoft released to the public earlier this week. As reported by Bleeping Computer, affected users have experience stuttering, inconsistent framerates, and slowdowns, even on fast PCs with modern components. Nvidia says the problem is caused
After Apple updated its privacy rules in 2021 to easily allow iOS users to opt out of all tracking by third-party apps, so many people opted out that the Electronic Frontier Foundation reported that Meta lost $10 billion in revenue over the next year. Meta's business model depends on selling user data to advertisers, and it seems that the owner of Facebook and Instagram sought new paths to continu

A Princeton professor, finding a little time for himself in the summer academic lull, emailed an old friend a couple months ago. Brian Kernighan said hello, asked how their US visit was going, and dropped off hu
Rocket Lab hits milestones with next launch. The company's next mission, a launch in mid-September from New Zealand's Mahia Peninsula, is a dedicated launch for Japanese Earth-imaging satellite constellation operator Synspective. It will also be Rocket Lab's 30th launch. Rocket Lab notes that, in addition, the mission will deliver its 150th payload and 300th Rutherford engine to space. Nine Ruther
I am not a data scientist. And while I know my way around a Jupyter notebook and have written a good amount of Python code, I do not profess to be anything close to a machine learning expert. So when I performed the first part of our no-code/low-code machine learning experiment and got better than a 90 percent accuracy rate on a model, I suspected I had done something wrong. If you haven't been fo
Some microprocessors from Intel and AMD are vulnerable to a newly discovered speculative execution attack that can covertly leak password data and other sensitive material, sending both chipmakers scrambling once again to contain what is proving to be a stubbornly persistent vulnerability. Researchers from ETH Zurich have named their attack Retbleed because it exploits a software defense known as
The world's first laptop to use the RISC-V open source instruction set architecture (ISA) will reportedly start shipping in September. The Roma laptop is available for preorder on Xcalibyte's website, but the site merely takes interested parties' information without providing much detail or any pricing. The laptop will start shipping in September, according to spokespeople from Xcalibyte, which di
Enlarge / Members of the public queue outside a pharmacy to receive COVID-19 antigen tests in Paris on January 6, 2022. Omicron subvariants BA.4 and BA.5 are on the rise in the European Union, spurring officials there to warn that a surge of COVID-19 cases will likely follow in the coming weeks. In an alert Monday, the European Center for Disease Prevention and Control cautioned that various facto
HP released its Dev One Linux laptop today. Aimed at coders, the 14-inch clamshell comes at a lower price than previous Ubuntu-based HP clamshells. Starting at $1,099, the Dev One begins to keep costs low by opting for an AMD, rather than Intel, CPU and skipping the discrete graphics card. HP's last Linux laptops, part of its ZBook workstation lineup, went well over $2,000 and offered up to Intel
Thirty years ago, on May 29, 1992, Apple announced its most groundbreaking and revolutionary product yet, the Newton MessagePad. It was released to great fanfare a year later, but as a product, it could only be described as a flop. Widely mocked in popular culture at the time, the Newton became a poster child for expensive but useless high-tech gadgets. Even though the device improved dramatically
When you turn off an iPhone, it doesn’t fully power down. Chips inside the device continue to run in a low-power mode that makes it possible to locate lost or stolen devices using the Find My feature or use credit cards and car keys after the battery dies. Now researchers have devised a way to abuse this always-on mechanism to run malware that remains active even when an iPhone appears to be power
After years of hinting, Nvidia announced yesterday that it would be open-sourcing part of its Linux GPU driver, as both Intel and AMD have done for years now. Previously, Linux users who wanted to avoid Nvidia's proprietary driver had to rely on reverse-engineered software like the Nouveau project, which worked best on older hardware and offered incomplete support at best for all of Nvidia's GPU f
Enlarge / Are we looking at an official Game Boy Advance emulator made by Nintendo? In most cases, the release of yet another classic console emulator for the Switch wouldn't be all that noteworthy. But experts tell Ars that a pair of Game Boy and Game Boy Advance emulators for the Switch that leaked online Monday show signs of being official products of Nintendo's European Research & Development
Last year, Apple enacted App Tracking Transparency, a mandatory policy that forbids app makers from tracking user activity across other apps without first receiving those users’ explicit permission. Privacy advocates praised the initiative, and Facebook warned it would spell certain doom for companies that rely on targeted advertising. However, research published last week suggests that ATT, as it
The teardown video depicted a somewhat complicated but not insurmountable process for getting inside that little metal rectangle. Once inside the device, there weren't many surprises. The video identified some ports, showed the removal of the logic board, and perhaps most notably, uncovered a dual-fan cooling system inside the machine. Further, iFixit talked about the much-discussed SSD swapping s
Rumors of Russian Internet services degrading have been greatly exaggerated, despite unprecedented announcements recently from two of the world’s biggest backbone providers that they were exiting the country following its invasion of Ukraine. Just as ISPs provide links connecting individuals or organizations to the Internet, backbone services are the service providers that connect ISPs in one part
Linux has yet another high-severity vulnerability that makes it easy for untrusted users to execute code capable of carrying out a host of malicious actions, including installing backdoors, creating unauthorized user accounts, and modifying scripts or binaries used by privileged services or apps. Dirty Pipe, as the vulnerability has been named, is among the most serious Linux threats to be disclos
If you're using either Dropbox or Microsoft OneDrive to sync files on a Mac, you'll want to pay attention to the release notes for today's macOS 12.3 beta: the update is deprecating a kernel extension used by both apps to download files on demand. The extension means that files are available when you need them but don't take up space on your disk when you don't. Apple says that "both service provi
Welcome to Android API level 31, aka Android 12. Google's latest OS had one of the weirdest rollouts ever. An anticlimactic source code release happened in the beginning of October, but if you wanted to run Android 12 on a device officially, you had to wait until Pixel 6 launch day, when Google also shipped Android 12 out to older Pixel devices. In a way, this was appropriate for Android 12: a Pix
John Carmack, seen here wearing an early prototype Oculus Rift headset. Oculus consulting CTO John Carmack has been bullish on the idea of "the metaverse" for a long time, as he'll be among the first to point out. But the id Software co-founder spent a good chunk of his wide-ranging Connect keynote Thursday sounding pretty skeptical of plans by the newly rebranded Meta (formerly Facebook) to actua

Oculus may have officially discontinued its low-end Oculus Go headset last year, but the company has one more "official" update to help future-proof the hardware. On Thursday, Oculus released an unlocked build of the Oculus Go operating system, allowing for "full root access" on more than 2 million existing units
Quick Google Stadia recap: Things have not been great. Google's AAA cloud gaming service launched in 2019 to middling reviews and since then has severely undershot Google's sales and usage estimates by hundreds of thousands of users. The company shut down its first-party studio, "Stadia Games & Entertainment (SG&E)," before it could ever develop a game, and it did so one week after lead executive
Imagine having unlimited attempts to guess someone's username and password without getting caught. That would make an ideal scenario for a stealthy threat actor—leaving server admins with little to no visibility into the attacker's actions, let alone the possibility of blocking them. A newly discovered bug in Microsoft Azure's Active Directory (AD) implementation allows just that: single-factor br
Enlarge / We don't recommend allowing btrfs to directly manage a complex array of disks—floppy or otherwise. Btrfs—short for "B-Tree File System" and frequently pronounced "butter" or "butter eff ess"—is the most advanced filesystem present in the mainline Linux kernel. In some ways, btrfs simply seeks to supplant ext4, the default filesystem for most Linux distributions. But btrfs also aims to pr
Enlarge / Be sure you know what you're getting into before buying and using unfamiliarly branded smartphones—especially international models not originally intended for your country. The Lithuanian National Cyber Security Centre (NCSC) recently published a security assessment of three recent-model Chinese-made smartphones—Huawei's P40 5G, Xiaomi's Mi 10T 5G, and OnePlus' 8T 5G.

Popular NPM package "pac-resolver" has fixed a severe remote code execution (RCE) flaw. The pac-resolver package receives over 3 million weekly downloads, extending this vulnerability to Node.js applications relying on the open source dependency. Pac-resolver touts itself as a module that accepts JavaScript proxy configuration files and generates a function for your app to map certain domains to u

This company has been in the messaging business for 16 years, meaning Google has been making messaging clients for longer than some of its rivals have existed. But thanks to a decade and a half of nearly constant strategy changes,
If this desktop doesn't look hauntingly familiar to you, you either didn't live through the 1990s—or perhaps just didn't live through them right.
